OPERATING MECHANISM FOR ANNUNCIATING SYSTEMS;

Application filed February 11, 1911.

Specification of Letters Patent. Patented Sept. 16, 1913.

Serial No. 608,073.

To all whom it may concern:

Be it known that I, FRED MICHAELIS, a citizen of the United States, residing at Bartlesville, in the county of Washington and State of Oklahoma, have invented certain new and useful Improvements in Operating Mechanism for 'Annunciating Systems and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to new and useful improvements in operating mechanism for annunciating systems, and other like de vices.

An object is the provision of a suitable clock controlled mechanism which is electrically connected to a hell or series of bells and which will audibly give notification of the time at different intervals or periods during the day by ringing the said hell or series of bells for different length periods of time.

Another object of this invention is to improve and simplify devices of this character, rendering them comparatively simple and inexpensive to manufacture, reliable and efiicient in use and readily operated.

In effecting these several desiderata, this invention resides in the novel features of construction, formations, combinations and arrangements of various elements to be hereinafter more fully described, claimed and illustrated in the drawing in which:

Figure 1 is a front elevation of a clock having my invention applied thereto; Fig. 2 is a plan view of the supporting plates and their connections; Fig. 3 is a vertical longitudinal sectional view taken on the line 6-?) of Fig. 2. Fig. 4: is a vertical longitudinal sectional view taken on the line bb of Fig. 2 but looking in the opposite direction from Fig. 3. Fig. 5 is an end view of the mechanism illustrated in Fig. 2; Fig. 6 is a plan view of one of the longitudinal disks and the wheel engaging the same; Fig. 7 is a fragmentary plan view of the plate and spring contacts supported thereon; Fig. 8 is a detail perspective view of one of the spring contacts.

Referring to the corresponding figures of the drawings by similar characters of reference the numeral 1 designates generally a clock casing or housing comprising front and rear walls 2 and 3 connected at their opposite vertical edges by side walls 4, and at their opposite ends by a cap or upper closure 5, and a base or lower closure 6. The front wall 2 has formed therein a substantially rectangular shaped opening 7 closed by a glass paneled door 8 hinged as at9 to one edge of the closure, and afiording a means whereby access may be had to the clock 10 when desired.

A pair of transversely extending supporting plates 11 and 12 are bolted or otherwise secured in vertical planes and in spaced parallel relation to each other within the casing 1 upon the base 6 and are retained against displacement by sleeves 13 located upon tie rods 14: .which extend through apertures 15 formed in the said plates.

A vertically. disposed power transmitting rod 16 is rotatably mounted in suitable brackets or bearings 17 extending from the outer face 'of the plate 12 and supports keyed to its upper terminal a beveled pinion 18 which meshes with a similar pinion 19 geared in any convenient manner to the. shaft 20 of the minute hand 21 of the clock 10. A'horizontally disposed disk 22 is keyed to the lower end of the shaft 16 and serves to assist in controlling the hereinafter tobe-described elements. A beveled pinion 23 is keyed to the shaft 16 slightly above the disk 22 and meshes with a similar pinion 24 carried by the rearwardly extending terminal of a shaft 25 journaled at its opposite ends in the plates 11 and 12. The intermediate portion of the shaft has splined thereon a worm 26 the spirally wound threads 27 g of which meshwith the teeth of a spur pinion 28 carried by a vertical shaft 29 the opposite reduced ends of which are journaled in a pair of inwardly extending parallel superimposed arms 30 formed upon a supporting plate 31 while to this said shaft 29 at a joint below the spur pinion 28 is fixed a horizontally disposed disk 32 similar to the beforementioned disk 22.

Aspring actuated shaft 33 is journaled between the plates 11 and 12 and is extended at the end adjacent the plate 11 and squared as at 34 to provide a grip for a key not shown thereby providing a means for winding this said shaft 33. A gear wheel 8 1* is fastened to the shaft 33 and adapted to mesh with a pinion 35 carried by the shaft 25 which connection serves to gradually rois not dependent upon the shaft '33 but-is T merely assisted and in reality receives motion through the before mentioned vertical; shaft 16 and clock 10.

A shaft 37 is journaled substantially in-i termediate of the plates 11 and 12 and carries keyed to the end -adjacent the plate "12 a hub 38 provided with a plurality of radially extending arms 39 the offset terminals 40 of which are adapted to rest upon the disk 22 and pass through the slots 41 formed therein upon the rotation of the said shaft 16. This shaft 37 is so connectedwith the minute hand that the movement of the disk in a position to permit of the passage of the arms 39 ther'ethrou'gh requires the space of five minutes. A disk42 is keyed to the oppositeend of the shaft 37 and is gladuated and numbered with characters 43 indic'ating the time in minutes from 5 'to 60 inclusive. A sleeve 14 is rotatable upon the shaft 37 and has formed upon oneend'thereof a hub 45 similar tothe hub 38 and carries a series of arms 46 similar to the arms '39 the offset ends 17 of which engage the disk 32 and pass through the slots 48 formed therein in the same manner as the beforem'entioned arms. The disk 32 is so connected to the clock as to move one space each hour permitting the disk 49 carried by the sleeve 4 1 to move one space each hour This disk is graduated in spaces bearing the numv bers'from 1 to 12 inclusive indicating hours.

In order to provide a means for rotating the shaft 37 and sleeve 4A: a shaft 50 is j ournaled between the ends of "the plates 11 and 12 and carries a sleeve '51 upon one end thereof "the end of which together with the shaft 5O is squared to provide 'a means wherebythey can be rotatedby suitable keys not shown. Springs 52 are attached to the sleeve 51 and shaft 50 and to convenient parts upon the plates '11 and 12 and serve to impart "a rotary movement to the shaft 37 r and sleeve 44 through the medium of suitable gear wheels 53 and intermeshing pinio'ns 545. I 7 A plate 55 is secured to the lower edge of the plate 11 and extends outwardly therefrom supporting a pair of contact springs 56 and 57 which springs are provided with loops 58 adapted to engage screws or the like 59 for the purpose of preventing their undesired displacement. The disks 42 and 459 are provided withoutwardly extending pins 60 and "61 adapted to engage the upwardly curved ends "62 of the spring contacts and either make or break the contact 'upon the rotation "of the said disks.

The ends of several of the pins :are bent laterally as at 63'to provide a means whereby the bells 64 will be caused to ring for a longer period of time by their engagement with the said spning'con-tacts 56 and 57.

Conductors G5 and 66 are connected to the eyes 67 and 68 formed upon the springs 56 and 57 one of which is broken between its ends as at 69 for connection with one or more batteries 70.

From the foregoing disclosures taken in connection with the accompanying drawings it will be manifest that a clo'ckcontrolled 'annunciating system is provided for which will fulfil all of the necessary requirements of such a device. I I
